Summary: An important article about one of the critical B complex vitamins that got lost in the rush to synthesize nutrients. Vitamin B4 is a vitamer of the B complex that promotes proper nerve impulse transmission, yet it is not recognized as an essential nutrient by modern science. In the report Oxford researcher Cyrill William Carter notes that in pigeons suffering heart block who had been fed a diet devoid of natural vitamin B complex, supplementation with vitamins B1 and B2 failed to resolve the problem. When supplementation was switched to a yeast extract, which naturally contained the then-unknown B4 vitamer in addition to vitamers B1 and B2, the heart block was resolved. Oxford University scientists worked for over a decade to resolve the relationship between vitamin B4 and vitamin B1. From the Biochemical Journal, 1934.
